Subject: For PR1028:
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=a10dc506c0ea79a9689101edb37b2de6c36aa188;p=oota-llvm.git

For PR1028:
Add the llvm.stacksave and llvm.stackrestore intrinsics that correspond
to the GCC builtins __builtin_stack_save and __builtin_stack_restore. This
allows the CBE to execute these builtins, and fixes:

   test/CodeGen/CBackend/2007-01-17-StackSaveNRestore.ll
   External/SPEC/CINT2000/176.gcc (CBE)

Patch by Gordon Henriksen.
